Application filed eptcraber 23, 19122. Serial No. 721,734.

To all whom it may concern Beit known that I, Jox-1N ARTHUR Toerixe, a citizen of the United States, "residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful lmprovcn'lentn in Nailing-CleatS, ot' which the following is a specification. y My invention relates to improvements; in nailing cleats, or Strips t'or securing pre-` pared sheets to the Sides or root'g of buildings.

One of the objects of my invention is to provide a cleat which Shall have the eornbincd features of minimum cost of construction and maximum strength and cllciency.

Another object of my invention in to at lain these combined .resulte in a device l'ormed simply by Vtolding', in a certain way, a flat sbeetmelal blank, Said blank suitably out for such `folding'.

Other and further objects of my invenlion will become apparent t0 those skilled in the art :from a consideration ot the following description ltaken in conjunctirm with the accompanying drawinll-.` whereinl `igure 1 is a. brokenaiway perepective view, Showing` cleats conetructed and ap plied to a roofingr in accordance with my invention; Fig. 2 a longitudinal Section on line of Fig. 1; Fie: 3 is a iragmem tary plan view; Fig. 4 is a cross Section on line 4-4 of Fig. 3; and Fig". 5 is a trag mentary view showing tbe blank from which the cleat may be made by Folding. and in dotted lines Showing the manner ot Jfolding?r such blank for attainment of the results hereafter mentioned. lin my allowed application Serial No. 683,122, filed March '11th, 1912 1 have disclosed a cleatvvberethe end or a blank is cut so as to be angularly At'oldable to close 4the ends of the cleat and provide at sue-.h

the apex of the cleat arch, the side walls, 12 and 13, slantingc downward therefrom. The

Side walls are provided along their lower` edges 1.4 and '15 with out 'ardly folded flat marginal baec (langes 1li and 17 for coaetion with the underlying rooting material A, as shown in Fig'. 1. Preferably, each base liange is eut away at its end as at ,18 so that the outer edge runs; into the told lel- (Aor 15) at the cxtreme end o'll the Strip. The end of the strip is notched as Shown in Fig. 5 to provide edges 19 and 20 convereinef inwardly tmvard the central line l1 from the pointe 21-21 where fold lines 14C and 15 meet the outer edges oithe respective base flanges 11i and 17.

22 and. 23 indicate 'folds extending ,eon vcrn'ing'ly inward toward the central line l1 from said foremost points C.l1-21. but at a more acute angle to said central line than the edges 19---20, and 11 indicates a fold lying1 in the central longitudinal line of the strip but bent inwardly inetead of outwardly. lt will thus be obecrvcd that the sides 21and25 (between 15)A and 20-23) effectively close the ends ol the cleat` and that the .folded portion (211 lll-25) adetpuitely supports the cleat when nails 26 are driven at intervals through the apex A11 and into the wall or roof structure to which the cleat in applied. Obviously also the anglerelation of the edges 10H20 a nd folds Z2-23 may be varied to make the -told 11. in the completed cleat. Stand vertically orat any desired inclination to the vertical, Said told acting. in any event, in the manner of a bracing! or arch structure between the nailreeeiving apex and the rootsurface. It will be further observed that the toldS 22 and 23 diverge downwardly from the apex 11 and cach constitute an apex or divide between the triangular wall 24 or 25 and the respective eide Wall 12 or 13, all the Walls therefore slanting downwardly from an apex. Thus this ,structure minimizes the material and Work required in its eonstruc tion by a novel formation and folding o1 the blank. while thc completed device lacks none of the -necessary features of Strength. effectiveness in shedding water` etc. It will be apparent. further, that changes may` be made in the precise showing herein made to elose its ends, each' said side wall portion so bent being triangular and joined to the similarly bent portion of the other side wall at a central fold.

3. ,A nailing cleat made of a strip of metal longitudinally folded along a central line to form a nail-receiving apex and opposite inclined side walls, the end of said strip being out and folded to provide folds diver-ging downwardly and outward from the end of said apex, the portion between said inclined folds bent inwardly along a central line to close the end of said cleat.

'4. A nailing cleat made of a strip of metal lonfgitudinalljr folded along a central line to orm a .nail-receiving apex and along lines diverging from said central line to form wall-dividing apices extending' divergingly from the central apex toward the two foremostpoints of the strip, the walls which extend inwardly from said diverging apices meeting at an inward center-line fold of the strip.

5. A nailing cleat made of a strip of 'metal folded longitudinally along a central line to forma nail-receiving apex and side walls, theends of saidcleat being also folded along lines diverging from said central lines, the ,and portion between said diverging folds bei notohed to form edges diverging' from said central line at less acute angle than said folds, and sai'd end portionbeing' folded inwardly alongrsaid-oentral line to bring said diverging edges inthe same plane with the edges of said side walls. l

6. A nailing cleat made of a strip of metal folded longitudinally along a central line to .i form a nail-receiving apex and side walls,` the ends of said cleat being'- also folded along lines wdiverging from said central lines, the end portion of the strip between Said diverging folds being notched to form edges diverging from said central line at less acute angle than said folds, and Asaid end portion being folded inwardly along said centralline to bring,- said diverging edges in the same pla-ne with the edges of said side walls, and base ianges extending outwardly from said edges of the side walls in .said plane.

7 A strip` of metal out to provide at each end two foremost points, and folded to provide a cleat having' a central longitudinal apex, and at each end folds and edges eonverging from the center of the strip tok said foremost points thereof. l

8. A strip of metal out to provide at its ends two foremost points one on each side of the longitudinal center, said strip folded in one direction along its central longitu-l dinal line to provide a 11ail-receiving,apex,j said apex terminatingat a point somewhat. behind said foremost points, and said strip 'folded in the opposite direction along the 75 portion of said central line which lies beyond said terminal point of the apex, and further `folded to provide folds and edges converging from the ends of the last recited central fold toward said foremost points.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
